Puzzles done this stream:
"Brötchenstempel" by Myxo
Logic Masters Germany: logic-masters....
SudokuPad: tinyurl.com/ub...
Sudoku: Place each of the digits 1-9 exactly once in each row, column and box.
Palindromes: The sequence of digits along a grey line reads the same forwards and backwards.
Sandwiches: Clues outside the grid indicate the sum of the digits between the 1 and 9 in that row or column (or the parity of that sum).
"Border Count Pentominous" by Gliperal
Logic Masters Germany: logic-masters....
SudokuPad: tinyurl.com/43...
Divide the grid into pentominoes, such that no two pentominoes of the same shape (including rotations and reflections) touch orthogonally. Clues outside the grid indicate the number of borders between pentominoes present in that row or column.
"Loop Compass" by Agent
SudokuPad: tinyurl.com/2s...
Draw a non-intersecting loop that travels orthogonally through the centers of some empty cells.
Each orthogonally connected group of cells not visited by the loop consists of a single region. Each region must contain exactly one compass.
A number in a compass indicates how many cells belong to its region that are further in the indicated direction than the compass itself.
"Yin Yang Killer Deconstruction [9x9]" by Christounet
Logic Masters Germany: logic-masters....
SudokuPad: tinyurl.com/3b...
Normal sudoku deconstruction apply : Fill the grid with 9 non-overlapping 3x3 square regions, such that each region contains the digits 1-9 once each and no digit repeats in any row or column. Cells outside regions do not contain digits.
Yin Yang : the whole 11x11 grid must form a valid yin yang grid, that is shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is fully shaded or fully unshaded.
Killer cages : Digits in a cage must not repeat. The number in the top left corner indicates either the sum of the digits of the shaded cells or the sum of the digits of the unshaded cells contained within that cage.
